CVE-2025-40213

Estado: AplazadaAlta (7.8)—

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: MGMT: fix crash in set_mesh_sync and set_mesh_complete

There is a BUG: KASAN: stack-out-of-bounds in set_mesh_sync due to memcpy from badly declared on-stack flexible array.

Another crash is in set_mesh_complete() due to double list_del via mgmt_pending_valid + mgmt_pending_remove.

Use DEFINE_FLEX to declare the flexible array right, and don't memcpy outside bounds.

As mgmt_pending_valid removes the cmd from list, use mgmt_pending_free, and also report status on error.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vulnerabilidad local (AV:L/PR:L) en kernel Linux que causa crash (DoS) y corrupción de memoria por stack-out-of-bounds en Bluetooth MGMT; requiere acceso local con permisos limitados para explotar.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
